Are old airbags killers?

Takata airbags may not be the only ones with some very serious problems. A new report from TheDetroitBureau.com claims that the National Highway Traffic Safety Administration has opened its second investigation into bad airbag inflators, and this time, they aren't from Takata. The focus of this latest case is on the airbag inflators in some 500,000 older Chrysler Town and Country minivans and Kia Optima sedans, all of which come from ARC Automotive. While the Takata case looks at problems stemming from the engineering and production process, the ARC investigation focuses on the age of the inflators. As TDB explains, airbag inflators are essentially what the military refers to as shaped charges, sort of like Claymores (for fans of the Call of Duty series). In combat, they blow up in a specific direction, protecting those behind the explosion, although in the case of airbags, the explosion "[creates] a precise rush of hot gases" that inflate the bags. NHTSA's worry is that with the increased average age of today's vehicles, years and years of being bounced, jolted, and shaken about and exposed to often-radical temperature changes have altered the nature of the explosives in these vehicles, causing too big of an explosion. "It may be a reasonable assumption that as these things age they deteriorate." – Analyst George Peterson "It may be a reasonable assumption that as these things age they deteriorate," analyst George Peterson told TheDetroitBureau.com. NHTSA boss Mark Rosekind backed up aging angle. "Cars are lasting on the road a lot longer than ever before," Rosekind told TDB, adding that seals could start breaking down. "Is aging now an issue? That's part of the investigation going on." NHTSA has only identified two "incidents" so far, although according to Center for Auto Safety Director Clarence Ditlow, there's genuine concern that there could be additional unidentified cases. "Could we have missed more? That could be the case," Ditlow told TDB, citing the misidentified deaths in the Takata investigation. Ditlow was quick to point out that, even in older vehicles, airbags are much more likely to protect than harm. "No one is saying you should disable your airbags," the safety advocate told TDB. "You're far more likely to be helped than hurt by one if they go off." At least one automaker, meanwhile, has already been advised of the investigation by NHTSA and is checking its airbags.

Hyundai and Kia to update EV brake lights; our tests show how they currently may not come on

Update: This article has been updated to reflect Kia's own service campaign announcement.  Hyundai will be launching a "field service campaign to update the EV brake light logic" on its Ioniq 5 as well as the Genesis GV60, Electrified GV70 and Electrified GV80. According to Hyundai's director of communications, Michael Stewart, the change will be make to new production vehicles and as part of free-of-charge service campaign that will launch in July for approximately 56,000 vehicles already on the road.  "Regardless of the accelerator pedal input, the brake lights will now turn on when the deceleration rate exceeds approximately 0.13 G," Stewart wrote in an e-mail to Autoblog. Since this article was originally published, Kia has announced it will be performing the same update to its EV6 and Niro EV. Kia is also part of the Hyundai Group. This change would seem to be in keeping with the behavior we have experienced in the Hyundai Ioniq 6, the firm's most recently introduced EV. We go into that behavior lower in this article.  This announcement comes in the wake of owner complaints as well as a test by Consumer Reports that found that most Hyundai, Genesis and Kia electric vehicles can come to a stop without their brake lights illuminating. This occurred when using those vehicles' most aggressive "i-Pedal" function that allows for so-called "one-pedal driving" where the driver can mostly rely upon the car's regenerative braking system (which is used to replenish the battery pack) to stop the car.  We tested this for ourselves this week as we are currently testing a Genesis Electrified GV70, and I personally own a 2023 Kia Niro EV Wave. I almost exclusively drive in i-Pedal mode. News Editor Joel Stocksdale tested the Hyundai Ioniq 6 in Michigan, and again, we will address his findings after the Genesis and Kia as they are completely different. I attached an action camera to the rear of each car and conducted the same test in both: Accelerate to 40 mph and come to a stop without touching the brake and, crucially, without lifting my foot fully off the throttle. The result as you can see below with the Niro is that the brake lights do not come on until around 3 mph when I fully lifted off the throttle and bring the car to a full stop. I could not bring the car to a full stop without fully lifting off the throttle.

2016: The year we talked about autonomy a bunch | Autoblog Podcast #497

This week on the Autoblog Podcast, Mike Austin and David Gluckman take a look back at one of the biggest topics of 2016: autonomous driving. The thing is, there was a lot of news about autonomous driving, but not much in the way of autonomous cars you can buy. They also talk about what they've been driving lately - there was a good turbocharged compact car and a not-so-good turbocharged compact car. And then we round out the year with a quick Spend My Money. The podcast will take a break next week, but we'll be back in the new year with reports from CES and the 2017 Detroit Auto Show. And we're lining up some fun guests for future recordings. The rundown is below. Remember, if you have a car-related question you'd like us to answer or you want buying advice of your very own, send a message or a voice memo to podcast at autoblog dot com. (If you record audio of a question with your phone and get it to us, you could hear your very own voice on the podcast. Neat, right?) And please send trivia questions! You'll get the honor of stumping your fellow listeners, and we'll thank you too.
